The doc -- obtained by TMZ -- confirms the baby was born at Cedars-Sinai in L.A. Thursday, February 1 at 4:43 PM and weighed in at 8 lbs. 9 oz. For once, the Jenner-Kardashian's go-to doc, Dr. Paul Crane, did NOT do the honors. Stormi was brought into this world by Dr. Thais Aliabadi.
As we reported ... Kylie announced Stormi's birth Sunday a couple hours before the Super Bowl, and released a vid about the pregnancy she managed to keep on the DL for 9 months.
